|Central coordinates||145o 45.00' East 15o 10.00' North|

Site description The proposed IBA is located in the central part of Saipan Island. The area includes the central Mount Topachau, which runs down the center of the island, Lake Susupe and associated wetlands, and the Kagman area and Forbidden Island. Parts of the Kagman area are protected as a Conservation Area and Lake Susupe is a Limited Take area.
Key Biodiversity The Tapochau-Susupe-Kagman IBA includes a number of areas with habitats important to critical bird species. The Kagman area and adjacent Forbidden Island are home to established populations of Micronesian Megapodes (Marshall pers. comm.), White-throated Ground-Doves, and Mariana Fruit-Doves; as well as the island’s largest population of Golden White-Eyes. Part of the Kagman area is protected by law as the Kagman Wildlife Conservation Area (Schroer, 2007). Lake Susupe, which is also regulated as a Limited Take Zone by CNMI law, is included both for its value as a wetland (and home for Mariana Common Moorhens) and because it is home to large numbers of Nightingale Reed Warblers. Mount Tapochau (surveyed as part of the Garapan area) is home to the bulk of the current population of Mariana Swiftlets, in addition to Saipan’s other critical species.
